OX400 Low Concentration Zirconia Oxygen Analyzer

Brand: Yokogawa Electric Corporation

The OX400 is a highly accurate and reliable low-concentration zirconia oxygen analyzer that is capable of measuring a wide range of concentrations, from 0 to 10 ppm up to 0 to 100% volume Oxygen. 

This is the latest oxygen analyzer from Yokogawa, and its development was based on the company’s long experience and strong track record with this technology.

 A proprietary new thin-film deposition technology was used in the zirconia sensor that creates a molecular bond between the zirconia element and the platinum layer. 

This prevents separation, enables a reduction in sensor size and ensures a high-speed response and long life. 

The OX400 can be used to control and monitor various semiconductor applications, and to control environment, air leakage into inert gas, and other processes.
Features
  • Long life and high-speed response
    • Thanks to the use of Yokogawa’s proprietary new thin-film deposition technology, the sensor has three times the lifespan of those used in our earlier products.
    • A cylindrical sensor design facilitates the replacement of measurement gases, thereby helping to assure a high-speed response.
  • High performance and high reliability
    • Superior repeatability and linearity even at low oxygen concentrations.
    • Either pump or aspirator sampling can be selected, depending on the application.
    • CE, CSA, etc. certification.
  • Built-in functions and a variety of self-diagnosis functions
    • Comes with multi selector, auto range, partial range, and pump on/off functions.
    • A variety of self-diagnosis functions are provided that detect malfunctions such as heater temperature error, temperature sensor burnout, and sensor resistance value error.
  • Superior maintainability
    • The sensor can be replaced on-site.
    • Compact and lightweight for easy installation.
